The components of Tenvir-EM (Truvada) are emtricitabine (200mg) and tenofovir disoproxil fumarate (300mg) TDF. These are the active ingredients used in HIV-negative people. This type of regimen with Tenvir EM is known as PrEP (pre-exposure prophylaxis), and is almost entirely successful in preventing HIV infection.
In terms of adverse consequences of using Tenvir EM, only a very small group of people have reported symptoms such as nausea, malaise, fever or skin rashes, which disappear immediately when PREP treatment is stopped. Pre-exposure prophylaxis treatment can be started and stopped in any situation and without the need for a pattern. For HIV-positive people, more specific medication is available and should be used instead of Ricovir or any other PrEP.
